Based on the molluscicidal activity of ginkgolic acids (GAs) isolated from Ginkgo biloba L, a series of Z/E isomers of GA analogues were prepared and evaluated for their molluscicidal activities against the host snail Oncomelania hupensis. The results and analysis of the structure-activity relationship revealed that the E-isomers showed better molluscicidal activities than their Z-isomers. Molluscicidal activities decreased with the shortening of the alkenyl chain lengths.

银杏酸(GAs)的杀螺活性,制备了一系列GAs类似物的Z/E异构体,并评估了它们对中间宿主钉螺(Oncomelania hupensis)的杀螺活性。结果及结构-活性关系分析表明,E-异构体显示出比其Z-异构体更好的杀螺活性。随着烯烃链长度的缩短,杀螺活性下降。
